3. DESCRIPTION OF PROGRAM OR FUNCTION

CALKUX performs a variety of functions related to the transmission of medical diagnostic x-ray beams through common shielding materials, including Pb, concrete, steel, gypsum wallboard, and plate glass.

4. METHODS

Given the broad beam transmission through a barrier, CALKUX will determine what thickness of material caused that transmission. Conversely, for a given barrier thickness, CALKUX will present the transmission and hardened HVL that result from penetration through this barrier.
CALKUX manipulates fits of the broad beam exposure transmission to the equation of Archer, et al. This same equation can be inverted to solve for barrier thickness x and the next HVL predicted for a beam that has penetrated a known barrier thickness. The fitting parameters are those published for constant potential 70, 100, 120, and 140 kVcp radiographic beams, 120 and 140 kVcp CT beams, and 50 kVp W and 30 and 35 kVp Mo mammography beams.
